Computer won't stay on

[Ryan1974]

My computer starts by itself but won't stay on! Turns on and off by itself! It will turn on sometimes long enough to get to a webpage but then shuts off! Turns on by itself without me pushing power button! Help please!

might want to check your power connection, maybe it isnt plugged into the wall correctly
